hi,
i'm trying to perform a ZCatalog.refreshCatalog() on a catalog with over
29,000 indexed objects. it churns for a good long time, and eventually fails
with a long set of tracebacks, of which i've included a sample at the end of
this message.
i think i understand the gist of the issue... it's trying to write an object
(probably a CatalogBrain) to the database, but this object's __dict__ contains
a value that is of type instancemethod, which isn't allowed for persistent
objects.
the problem is that i can't figure out which specific objects are causing the
problem. i've used pdb.post_mortem to get a debug prompt way down in the
traceback, but the code goes in and out of C modules, so i'm missing a lot of
what's happening. and when i interactively peek at the objects that are being
indexed when the error happens, there doesn't seem to be anything wrong, and i
can index the objects w/ no problem. i've even tried dropping the
subtransaction threshold down to 1, so it will try to commit a savepoint after
every object, but none of the objects being indexed seemed to have any problems.
i CAN verify that the instancemethod that is causing the problem renders like
this:
bound method SessionDataManager.getSessionData of SessionDataManager at
/session_data_manager
even that hasn't proven enough for me to concretely identify the source of the
problem, though.
i've been working on this for a full day already, and am not sure how to
proceed. does anyone have any debugging tips that might help me figure out
what, exactly, is causing the reindex attempts to blow up?
thanks!
